i've got the chance to get a Gamma 7000 ES, any good?

the timing is absolutely perfect. The coach at my school is selling the strining machine, Gamma 7000 ES. Wants $600 bucks for it. :shock:

It's a 6 point mount, with electronic tensioning. It's roughly 5 years old i think, and the tension head was just replaced a month ago with a "high quality metal one" and the clamps are gonna be replaced before selling it.

Is this a good deal? economically it's cheaper than my plan to get a table top crank machine, and then buying the wise head. Just wanted to see if anyone here has feedback on it.
